Facade sealing in Notting Dale

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have new sealant peeling off old mastic and water coming in around window frames, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Notting Dale is the same: the right product in a properly prepared joint.

Around Notting Dale, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Questions about Notting Dale

Will you plan work around the academic year at somewhere like Imperial College London?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Can you cope with the access rules in a London building?

Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

How do we ask for a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or use the quote form. Include photographs or drawings if you have them.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

What do you charge?

There isn’t a price list, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Cost factors for facade joints

Your fixed quote is built from the real scope. It allows for:

  • The product specified
  • Whether old sealant has to be cut out first
  • Any access equipment needed
  • The total length or number of joints

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • Whether the building will be occupied during the work
  • Clear photos of the problem areas
  • Any dates the work must fit around
  • Drawings or a marked-up plan, if available

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Walk the elevations once or twice a year
  • Plan facade sealing alongside redecoration
  • Report water ingress at frames as soon as it shows
  • Keep sills, gutters and drainage paths clear

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed instead of soaking the joints.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

Different surfaces, different methods

Window and door perimeters

Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.

Cladding panel joints

Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. In Notting Dale, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached
  • Point out any areas we must not close
